It is the backbone communications architecture for NVT's range of IP transmission devices. TBus supports all forms of coax and UTP cable, as well as 18/2, 2-wire (un-twisted wire), and STP (shielded twisted-pair) in any combination of star, peer-to-peer, or daisy-chain cabling topology.

In addition, TBus delivers 56VDC power for remote transceivers as well as their remote PoE devices (IP cameras, etc.) Loads of up to 1 amp are possible, supporting high power PoE+ devices up to 50 watts. TBus supports advanced 128-bit AES encrypted network speeds of up to 200 Mbps. Data distances of 8,000ft are possible on RG59/U.

TBus transmitters include the single-port NV-ET1801 and the 4-port NV-ET1804 TBus receivers include the 4-port NV-ER1804, the 8-port NV-ER1808i, and the 16-port NV-1816i. The 8- and 16-port receivers are 1U rack-mountable, and contain browser-based management tools.
